Territory brake problems

I HAVE just put my 2004 AWD Territory in for a service with my Ford dealer. Apart from doing the brake-hose replacement I was told the front lower ball joints were worn and needed to be replaced at a cost of about $700. I was also told the steering fluid needed to be flushed and replaced because it was burnt, and the brake system had to be flushed and refilled. The total cost of the service came to $1500. A ``noisy'' front end was brought to their attention in mid-2005 and again in 2006, and I was told this was related to the braking set-up. The vehicle has done less than 18,000km and is always serviced by Ford.
